Yi Seong-gye, a prominent military leader during the Goryeo dynasty, ended the regime in 1392 by leveraging the support of disgruntled scholar-officials (sadaebu).12

These officials, who favored neo-Confucianism over the prevailing Buddhist influence, sought significant land reform to address the economic instability caused by powerful aristocrats who had concentrated land ownership and reduced state tax revenue. With the backing of these reformers, Yi Seong-gye seized power, implemented a new land-distribution system based on official rank, and successfully drove out the last king of Goryeo.12

Following these events, Yi Seong-gye ascended the throne, establishing the Joseon (Yi) dynasty and moving the capital to Hanyang, modern-day Seoul.12
